PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 382,345, dated May 8,1888. Application filed January 20, 1887. Serial No. 224,968. (Nomodel.)

7 To all whom, it may concern.-

Be it known that I, THOMAS D. WORRALL, a citizen of the United States,residing at Lynn, in the county of Essex and-State of Massachusetts,have invented new and useful Improvements in Printing-Presses forPrinting in One or More Colors, for which I desire to obtain LettersPatent, of which the following is a specification. I

My invention relates to improvements in presses for printing in one ormore colors,and for printing several sheets of paper from one and thesame form, and for devices for holding type in the bed of the saidpress, as hereinafter described and claimed.

To enable others skilled in the art to construct and use my invention itis herein described as follows.

Fig. I is a front view of my printing-press. Fig. II is an end view ofthe same. Fig. III is a section showing the device by which thesaturated printing-paper or other fabric and the paper to be printed arefed through the press over the printing-type. Fig. IV are detachedrollers or cylinders, showing how'a number of sheets can be printed atone and the same operation. Fig. V is one of the rollers for carrying anumber of narrow strips of saturated colored paper or other fabricacross the face of the type. Fig. VI is a cross section of the movableplaten, with its impression-lever, showing the manner in which theprinted impression is made. Fig. VII is a top view of one of the movableplatens. Fig. VIII is the upper side of the bed with its flanges,movable cross-bars for holding the type in position, and an improvedtype-holder. Fig. IX is a vertical view of one of the flanges, showingthe manner of its attachment to the bed of the press. Fig. X is theunder side of the bed of the press. Fig. XI is a skeleton paperholder orfly for holding saturated printingpaper. Fig. XII is a view of themultiform paper-holder for use when required to print detached leaves ofpaper, cards, envelopes, Ste.

A is the frame of the press, held together by the cross-bars a and thecross-rods B, and the latter being held securely in place by thescrew-nuts b.

c is the front end of the movable platen C.

D is an impression-lever journaled into the platen at the dotted linesd, Fig. VII, and more clearly seen at d in Fig. VI.

At (1, in lever D, is a hook or crow-bill with an inner wedge-shapedsurface, made to impinge against the under side of the rod B whenoperated by the lever D and made to engage the rod B. The wedge shape isshown by the dotted line extending from the cross-rod B to the hook orcrow-bill, at d.

For convenience in description, I will call the two cross-rodsB thefront and rear crossrods B. The movable platens O U are journaled to therear cross rod B at c, and are made to move laterally over the wholesurface of the bed of the press, so as to enable them to make aprintedimpression in any desired part of the bed without printing any otherpart of a sheet that may lay for the time being on the press. There aretwo or more of these movable platens, one of which may be used to printa letter or bill head, and the other to print the name, date, Ste, aftera letter has been printed,without again printing the head;

or, after the letter has been written bypen or I impression.

It will be seen that in this device I have the advantage of the leverand wedge, the wedge acting on the lower edge of the bar B, forcing downthe platen, and thus insuring a good impression.

Fig. X is the under side of the bed of the press, so constructed that itmay be raised or lowered, so as to regulate the impression on the type.E are diagonal braces in the casting for strengtheningthe bed. Fourholes -one at each corner, at e--are countersunk to receive the ends ofset-screws, as seen at F in Fig. II, by means of which the bed is raisedor lowered to regulate the impression.

Fig. VIII is the upper side of the bed H, in

which, at G, are provided flanges for holding the form of type in thebed. G, Fig. IX, is a front view of one of these flanges, in which, atg, is a recess running nearly across the bed. His the edge of the'bed,to which these flanges are securely fastened by screws, as seen at h.These flanges are secured to the bed so as to be flush with both edgesthereof, and thus a slot is formed by the recess 9.

I are one or more cross-bars, made to slide back and forth in this slot9 over the whole length of the bed, for the purpose of holding the typein any desired part thereof. These sliding cross-bars are held securelyin place by thumb or other nuts, 1', thus firmly holding the type inposition. These cross-bars may be slotted, so as to hold type for thename of a writer, with date or other useful matter, and thus may be madeto move to the end of a long or short letter, as may be required, afterthe letter has been written by pen .or otherwise. This device is clearlyseen in the drawings, Fig. VIII, at It.

Ink may be applied to the face of the type in this press as in anyother, butit is my purpose generally to dispense with its use and tosubstitute therefor paper, or other fabric saturated in pigment, for dryprinting,and which, when dry or partially dry, is placed between thetype and the paper to be printed. I do this as follows,viz: At J, Figs.II and III, are

' strips of paper over the rollers 3, 5, and 7, as

seen rollers extending across the press and at both ends thereof. Uponthese rollers I wind my prepared paper and let it extend across thewhole length of the press, .over the face of the type and between theface of the type and the platen. By laying the print-paper on the top ofthis-prepared paper or other prepared fabric over the type and drawingdown the platen, as'above described, I make my printed impression in onecolor. At J, Iinsert a second pair of rollers, turned into aset ofcontinuous reels, as seen at J in Fig. V. These I fill with narrowribbons, of paper, silk, or other suitable fabric, saturated in different colors from that of the base paper before alluded to, and stretchthem over the face of the first continuous sheet, and by printing, asbefore, I have printed the base in one and the stripes in many colors.The printpaper can be fed in single sheets by hand, as seen in Fig..XII, or from a continuous roll, as seen in the drawings at J in Fig.III.

I find from experiments made that by duplicating the above arrangement Ican print several copies at one and the same time. I do this in themanner illustrated in Fig. IV, in which rollers 1, 3, 5, and 7 carry mysaturated paper, and rollers 2, 4, and 6 the paper to be printed. Byinterposing the narrow in the process above described, I can printseveral copies in colors at one and the same impression.

Rollers for carrying colored strips can be arranged to carry the stripsacross the press diagonally as well as longitudinally, and thus givecheckered printing in many colors.

\Vhere it is desirable to print a number of copies at one and the sametime from single leaves, instead of continuous rolls of paper, I attachto the rollers J or to the frame of the press a number of thin fly orpaper frames or holders. Said flies may be made of card-board or thinmetal frames, as shown at Q, Fig. XI.- Over these flies are stretchedthe saturated printing-sheets. At the lower end of each of these flies Imake two or .more perforations, by means of which they are kept in placeon an open ring, which acts as a common hinge, holding them in place andadmitting of their being lowered or raised, or opened and shut, like theleaves of a book. This device is seen at Fig. XII, in which K is theopen ring, two of which are made to'slip over the rod or roller J, atj,as seen in Fig. II, one at each end of said roller. The aperturej inFig. XII is that through which the roller passes when placing the openrings or fly-holders in position. The flies being threaded or hinged onthe open rings are in position to be folded down upon the face of thetype T, lying on the bed of the press. In Fig. XII all but one are seenin fan shape standing at L. The'one at L is turned down on the face ofthe type. One being thus brought down on the type, I now lay on it aloose sheet of paper to be printed. I then bring down a second fly, withits saturated paper, and place it on a second loose sheet of paper to beprinted, and so continue until I have brought down as many as can beclearly printed at one operation, and when all are thus ready I bringdown the platen and make the impression in the man ner previouslydescribed.

ICO

By stretching the narrow ribbons across alternate flies printing incolors can be done as in the above-described method; but in order to doprinting either on rolls of paper or loose sheets both devices arenecessary in every press-one for rolls and one for loose sheets.

One object of my invention is to supply a press for office or popularuse; and to this end I have endeavored to simplify the method of holdingtype in the bed of the press, by inventing a new and useful type-holder,which consists of any desired number of strips or plates of metal, ineach end of which I drill holes, through which connecting screw-rods arepassed. The outside plate is tapped at each end to receive thescrew-rods. I divide these strips by means of slotted plates of theexact thickness of the type to be used, leaving the openings to receivethe type, and I make them changeable, so as to receive different kindsof type. The short dividing-plates are slotted, so as to admit of theirbeing pushed against the rows of type to hold them securely in place,and the slots are open at one end, so that the plates can be readilywithdrawn and others of greater-or less thickness inserted, as thedifferent thickness of type may demand.

When the desiredform is set up, it is securely locked by means of therod running through the whole. This device is shown in its true place-onthe bed of my press, 0, Fig. VIII, in which M is one of the plates,lying on its side, with the holes drilled through the two ends m m.

N is the slotted dividing-plate, also lying on its side. At n, in M, theslotted plate is seen in position.

P P are the connecting and locking rods, passing through the series ofplates to p p, where they are tapped into the plates. The writing on theform is designed to show how the dividing slotted plates are used fordifferent thicknesses of type.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the type-bed, of a platen, pivoted,substantially as described, so as to be capable of lateral as well asvertical movement.

2. The combination, with the type-bed, of a series ofindependentlypivoted platens.

3. The combination, with the type-bed, of a series ofindependently-pivoted and laterallymovable platens.

4. The combination, with the pivoted platen and adjustable bed, of theoperating-lever pivoted directly to the platen, and the cross-rodextending the whole length of the press-frame, the lever engaging therod after the manner of a wedge.

5. In combination with the bed andplaten a series of holders furnishedwith saturated paper or strips, the strips being of difiterent colors,whereby several impressions in one or more colors may be made at once.

6. In combination, the slotted bed-frame and the laterally-adjustabletype-holders.

7. The type-holder composed of perforated bars, interposed slottedadjustable and interchangeable strips corresponding to the thickness ofthe type, and the clamping or lookingup screws.
